@wdw4rfam - In 2015, they did hand out Standby wristbands a few hours prior to each concert.
Here's my post from 2015 after I attended David Cook's concert:
"Standby wristbands were given out for the Eat to the Beat concerts. Those with the Standby wristbands were seated in the front left of the amphitheater. Wristbands for the corresponding shows were handed out at 1:00, 3:00, and 5:00."
I'm not sure what they did last year (2016).
